10 Best External Backup Drive For Mac 2025 in the United States

The G-Technology 12TB G-DRIVE with Thunderbolt 3 and USB-C is a robust external backup drive for Mac users. With a substantial storage capacity of 12TB, it provides ample space for large files and extensive backups. The dual Thunderbolt 3 ports and single USB-C port with USB 3.1 support allow for high-speed data transfers, which is ideal for users who need to move large amounts of data quickly. The daisy-chaining capability is a robust feature, enabling the connection of up to 5 additional devices, which can be convenient for users with extensive setups. Its all-aluminum casing not only makes it durable but also adds a sleek, stylish look to your desktop setup.

The 7200 RPM rotational speed ensures efficient performance, making it suitable for both professional and personal use. The 5-year limited warranty from the manufacturer offers peace of mind regarding longevity and reliability. A notable drawback is its size and weight; measuring 8.27 x 5.12 x 1.79 inches and weighing 2.73 pounds, it is less portable and more suited for a stationary setup. Additionally, while marketed as portable, it may not be as convenient to carry around compared to smaller, lighter drives.

The lack of built-in backup software might be a downside for users looking for an integrated solution, though this can be mitigated by using third-party backup options. This drive is best suited for Mac users needing a high-capacity, reliable, and durable external drive for their desktop setup.

The LaCie d2 Professional 10TB External Hard Drive boasts substantial storage capacity, making it an excellent option for Mac users who need to manage large files or extensive media libraries. Its 10TB capacity allows you to store a vast amount of data, while the 7200 RPM speed ensures that data transfers are relatively quick at up to 240MB/s.

This drive connects seamlessly with USB-C and Thunderbolt 3 interfaces, which are common on modern Mac computers, providing ease of use and compatibility. The aluminum form factor is designed to reduce noise and vibration, offering a quieter working environment, and the BarraCuda Pro enterprise-class drive inside ensures durability and reliability for long-term use.

The 5-year warranty and included recovery service offer peace of mind, especially for those dealing with critical or sensitive data. However, this drive is best suited for desktop use due to its size and weight, which makes it less portable. While it does offer Wi-Fi connectivity, the primary interface remains USB 3.0. Despite these minor drawbacks, the LaCie d2 Professional is a solid choice for creative professionals or anyone needing substantial, reliable storage for their Mac.

The SanDisk 4TB Desk Drive SSD is a solid choice for Mac users needing extensive external storage. With a generous 4TB capacity, it offers ample space for large photo, video, and music collections, as well as important documents. The SSD technology ensures fast performance, with read speeds up to 1000MB/s, making it significantly quicker than traditional hard drives. This speed not only facilitates rapid file transfers but also makes backing up data more efficient.

The included software for automatic backups adds convenience, though it does require download, installation, and possibly user registration. Connectivity is straightforward with the USB-C and USB 3.2 Gen 2 ports, ensuring compatibility with contemporary Mac devices. The drive comes pre-formatted with exFAT, so it's ready to use out of the box. However, as a desktop SSD, it’s larger and less portable compared to more compact, portable SSDs.

At 3.9 x 3.9 x 3.9 inches and weighing 9.4 ounces, it's designed to stay in a fixed location on your desk. The design is compact enough to not take up much desk space, though. The drive also boasts good durability, typical of SSDs, and comes with data recovery services, which adds an extra layer of security for your data. One limitation is that it requires an external AC power adapter, which might be a downside if you prefer a more streamlined setup. The SanDisk 4TB Desk Drive SSD is ideal for users who need large, fast, and reliable storage for their Mac, particularly in a stationary setting where portability is less of a concern.
